Just thought of one more issue with these trannys. There is a solenoid pack in the valve body of this tranny and it has an integral printed circuit board which is not protected from metalic wear debris as the later models were. The solenoid pack has four on-off valves (three on-off and one pulse width modulated on later versions) and one variable force solenoid valve to schedule the shifts and control the transmission operating pressure. Metal fines can settle on this PC board and cause short circuits and erratic shifts due to inappropriate circuits being turned on and off.

If you can turn off the locking converter with a switch on either the dash or the shift stalk try that and see if the problem goes away. If that solves the problem then you need a new torque converter
